Frequently Asked Questions
Which number bases does this support?
Binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16) are all converted simultaneously from whichever field you type into.
Does it validate that my input is valid for the chosen base?
Yes - for example, typing an "8" or "9" into the binary field will be flagged as invalid, since those digits don't exist in base 2.
Can I convert very large numbers?
Yes, though extremely large values may be limited by standard JavaScript number precision - for typical programming and debugging use (IP addresses, color codes, memory values), it handles the full practical range.
